History
Szolnok-Doboka county was formed in 1876, when Belső-Szolnok county (its center was Dés/Dej), most of Doboka county (its center was Doboka/Dăbâca at first, later Szamosújvár/Gherla) and the eastern part of the Kővárvidék/Chioar district were united.
In 1920, by the Treaty of Trianon, the county became part of Romania, except from 1940 until the end of World War II, when it was returned to Hungary by the Second Vienna Award, with a slightly modified territory. The territory of the county is now divided between the Romanian counties of Cluj (the center and south, a.o. Dej), Maramureș (the north), Bistrița-Năsăud (the east) and Sălaj (the west).
